HYDROPHOBIC AND BREATHABLE NANOMEMBRANE FOR FOOD PACKAGE MATERIAL BY MIMICKING COCOON'S STRUCTURE

ABSTRACT
The aim of this study was to investigate the cross-linked poly(vinyl alcohol) nanofibrous mats treated by flourinated alkane in supercritical carbon dioxide medium. The surface morphology and chemical structure of electrospun mats were analyzed by scanning electron microscopy and Fourier transform infrared. The results showed that the treated mats could maintain their integrity and fibrous morphology as well as their porous structure after being treated. However, the wettability was changed greatly, the average contact angle of treated nanofibrous mats increased from its original value of 28° to 134°, revealing that the treated mats had good water repellent properties. The paper concluded that the hydrophobic and breathable mats with porous structure might be an excellent candidate for food package materials.
